STOVE.

SPECIFICATION forming part of Letters Patent No.410,143, dated September3, 1889;

Application filed July 20, 1888. Serial No. 280,471. (No model.)

To aZZ whom it may concern.-

Be it known that I, ALPHEUS M. BLAKES- LEY, of the city of Rock Island,in the county of Rock Island and State of Illinois, have inventedcertain new and useful Improvements in Stoves, of which the following isa specification.

My invention relates particularly to that class of heating-stovesfamiliarly known to the trade as Oak Stoves; and it is designed toutilize as far as practicable the heat produced by the fuel consumedtherein by causing it to Warm a current of external air in a chamber orflue near to, alongside of, in, or partially or wholly surrounded by thefire-pot or fire-chamber with its inlet and exit orifices disconnectedtherefrom, the heat of the fire causing the air in such chamber or flueto become heated and to ascend, and thereby effecting a continuouscirculation of air through such chamber.

My invention will operate effectively and be of practical utility whenapplied in connect-ion with any variety or class of stoves adaptedwholly or in part to furnish heat; but for convenience I will illustrateit in the drawings and describe it in the specification as embodied inthe Riverside Oak Stove as at present manufactured by the Rock IslandStove Company.

In the drawings, Figure 1 is a rear elevation of a stove containing myinvention. Fig. 2 is a vertical section on the line 00 on. Fig. 3 is adetached view in perspective of the circulating air-chamber F. Fig. 4 isan elevation of Fig. 3. Fig. 5 is a plan view of the base of the stove,with the air flue or chamber in section on the line y y, Fig. 2. Fig. 6is a plan view of the top plate. Fig. 7 is a plan View of the concentricrings next below the top plate. Fig. 8 is the cover. Fig. 9 is aperspective of the central concentric rings.

A is the base; B, the fire-pot; O, the cylindrical fire-chamber orcombustion-chamber.

D is the top plate, having at one side a collar d, to receive thesmoke-pipe, and a central opening at d, with preferably a flangedepending from the inner edge of the plate.

01 is the cover, provided with openings for the passage of heated air.

D is a ring interposed between the top of the cylinder 0 and the topplate D, the outer edge of which fits over a flange (i d is a verticalring arranged concentric with the ring D and connected therewith byarms.

The lower part of the circulating air-chamber is shown at E, and ofwhich e e e represent the side walls and onterwall, the part a of theinner wall being formed preferably by a flat section of thefire-chamber,the lower part a of that inner wall being a part of the necting thelower end of the section F to the.

lower section E. The upper end of the section F has a flaring orenlarged part or collar f, adapted to make a close-fitting joint with aring or flange, to 'be described; or a separate flange or collar f (seeFig.2) may be attached to the upper end of this section.

F is a ring or flange connected by'arms with a smaller concentric ringor flange f which engages with the expanded part or up-- per end of thepartF. The ring F is supported between the upper end of the lowersection of the fire-chamber and the lower part of the upper section,these parts being socured to each other and to the ring D and fire-potand base by rods 1) b or in anyother usual or approved way. The uppersection G of the circulating flue or chamber is preferably circular incross-section and of uniform diameter at top and bottom, being supportedwithin the rings (1 f From the above description and the drawings itwill be readily understood that when the stove is in operation theproduct of combustion follows substantially the path indicated by thearrow 1 on Fig. 2, and that a current of air willbe drawn at the bottomof the circulating-flue, will be heated as itpasses through the sectionsF G, and will be discharged through the openings of the cover 01 intothe surrounding apartment. With prop- IOC erly-fitted joints between theparts none of the products of combustion will be mingled with thatheated column of air.

Of course a hot-air flue may be connected with this circulating-flue andconduct the heated air to an apartment above the one in which the stoveis situated. 7

As will be seen, the section E of the air adjacent to and utilizing theheat from the firepot is separated from and-out of direct contact withthe fire, thus preventing the beveling out of the walls of the saidsection and in no wise interfering with the use of a grate of anydesired construction. 7 W

I deem it important that the section E be a part of the stove, and thatthe inner wall thereof be formed by the adjacent wall of thefire-chamber and base, thus effecting a saving of material and providingfor the partial warming of the air in its passage through said section.

I claim- 1. In a stove, a circulating ail-chamber separated from andextending to a point over and above the fire-pot, the outer wall of thefire-pot forming the inner wall of the airchamber, substantially as setforth.

2. In a stove, a circulating air-chamberconsisting of a section Eadjacent to and separated from the fire-pot by the fire-pot wall, whichforms the inner wall of said section, a section G within the stove, andan inclined sect-ion F, connecting the sections E and G, substantiallyas described.

8. In a stove, a circulating air-chamber consisting of a section Eexterior to and adjacent to the ire-pot, the wall of which forms theinner wall of said section, a section G within the stove-body, and aninclined section F above the fire-pot communicating with the section Ethrough an opening in the said stove-body, and also connected with thesection G, substantially as described.

l. In combination with a stove-body, an air-circulating chamberconsisting of a lower section E, an upper section G, and an inclinedsection F, connecting the other sections, and having a flange c on oneend and an enlarged part or collar on the other end, said collar andflange being at substantially right angles to each other, andsupporting-rings for the sections F and G, substantially as described.

5. In a stove, the combination, with the cy lindrical chamber 0, of thetop plate, the cover, and the ring D, interposed between the top plateand formed with depending flange and upwardly-exten ding flange 61 overwhich the outeredge of the cap fits, substantially as shown anddescribed.

6, In a stove, the combination,witl1 the sectional cylinder 0, the topplate D, and ring D, having vertically-extending flanges, of the ring Fand the rods 1) b, engaging said rings and serving to hold the rings andsections together, substantially as and for the purpose specified, 1

'7. In astove, the combination,with the cylinder C in sections, the topplate D, having central openings d and depending flange,

and the ring D, formed with the inner concentric ring d of the ring F,formed with the inner concentric ring f the upper section G of thecirculating-flue held in said inner rings, and the rods 19 1),connecting the rings F and D, substantially as and for the purposespecified.
